a good question. I think my answer is yes, but it's a qualified yes. I can only answer from a personal standpoint:
When I was in my 20s and spending too much time in bars and cafes, it seemed important that everyone should agree with my (undoubtedly correct) opinions on the best music, the best movies, the best books, the best politics etc.
Now that I'm older, it seems much more important to actually DO, myself, those things I think worthy and useful, and/or to actively support others who, in my mind, are putting the worthy and useful out into the world.
I think if we're doing that, and doing it without too much rancour, we are allowed to HOPE that our opinions about the worthy and useful win out in the end.
I think most have an notion of what "quality" work is, and would like to see that work flourish; but there's a wide range of opinions about what constitutes that quality. It's in the realm of ideas/discussions and in our choices that we cast our vote for what we consider best.
In short, yes, actively proselytize in words and in deeds, but expect and accept that others (of differing views) will be doing the same, and that in the end it will be a combination of much larger/grander forces that 'settles' the issue, at least temporarily, until the next generation -- upon which the responsibility will next fall.
